9.3 Procedure for UPS Start-Up: without power initially supplied to the load
This procedure should be followed when turning on the UPS from a fully powered down condition - i.e. where the load

seconds the Inverter output healthy ( 4 - steady green ) and Battery unavailable (3) will light and also red led (13)
will illuminate.
The Display screen will show the following:
